What Klaviyo does

Where Klaviyo is strong

• Store data arrives ready to use: Shopify, WooCommerce, Magento, BigCommerce and 350+ marketplace apps feed orders, products and browsing events into profiles.
• Prebuilt ecommerce flows, such as abandoned cart, browse abandonment and back in stock, with revenue attributed to each campaign and flow.
• Segmentation on purchase history and behaviour that marketers build without a data team.
• A broad MCP server with more than 260 tools that can create, schedule and send campaigns, create flows and manage segments, plus a CLI generated from the full API.

Why teams look elsewhere

1. 01Receipts, password resets and alerts have to go out the moment they are triggered. Klaviyo sends transactional email from flows triggered by an event (other flow types need a request through support), and each transactional message is reviewed before Klaviyo approves it. Editing an approved message removes its transactional status, and it goes back for review. That works for an order confirmation you write once. It slows a product team that changes its account, security and billing messages every sprint.
2. 02The bill should follow the messages you send. Since February 2025 Klaviyo bills on active profiles: every profile you can still email, text or push counts toward your tier, whether or not you messaged it that month. A product with a large signup base and a small, active audience pays for the whole base, and SMS credits sit on top.
3. 03A free plan you can build a product on. Klaviyo's free plan stops at 250 active profiles and 500 emails a month. SuprSend's free plan covers 10,000 notifications a month across every channel, with the in-app inbox included.
4. 04Users need to be reached inside the product and in the browser. Klaviyo's push reaches iOS and Android apps you connect; its docs describe no web push. Its in-app forms are pop-ups, and there is no persistent feed a user can come back to. Klaviyo's channel list includes no Slack or Microsoft Teams. A product that notifies users about activity, approvals or mentions ends up adding a second tool for these.
5. 05Each of your customers is a business with its own setup. Klaviyo models people: profiles, their events and your catalog. Its docs list no tenant model that gives each business customer its own branding, templates, preferences and sending setup inside one account. B2B products end up keeping that logic in their own code.
6. 06Engineering wants notification changes reviewed like code. Klaviyo's MCP server and new CLI both call the API one operation at a time. The CLI docs say the earlier workflow that kept flows and campaigns as local JSON files has been retired, and testing runs in a separate test account. Klaviyo's docs list no promotion of a change from staging to production. A team that wants every message change in a pull request has to build that layer itself.

1.SuprSend

Best for running transactional, product and engagement notifications from one platform, with engineering, product and growth teams working in it alongside their agents

What SuprSend is

SuprSend is a US company, founded in 2022, that runs every notification a product sends from one platform, from transactional alerts to engagement campaigns. Engineering, product and growth teams work in it alongside their agents.

A complete orchestration engine

WorkflowsA workflow engine with branches, conditions, delays, throttling, data fetch and webhook steps, and sends in each user's timezone. One send step reaches the user's channels in your order. Built visually, through the CLI or by an agent, with version history and rollback. Builder on every plan; throttling, fetch, webhook and timezone from Essentials.

In-app inboxA real-time bell and feed with read state synced across devices, tabs, toasts and per-tenant feeds, on six client SDKs, embedded or headless. Every plan, Free included.

User preferencesUsers opt in or out per category and channel, in a preference centre you embed or host, and every send respects it. Business.

Per-tenant setupsEach of your customers gets its own branding, templates, preferences and provider routing. Business add-on, Enterprise.

Batching and digestsCollect events over a window and send one message, at a time the user picks, with batching and digests. Business.

TemplatingEditors for every channel, variants by tenant, user or language, and version history with rollback. Every plan; translation files on Business.

ObservabilityStep-by-step workflow logs and message logs with the provider's error, kept 30 days on Free and 90 on paid plans, with warehouse sync on Business.

Retries and fallbackBring your own providers; if one does not confirm delivery, the next one sends. Essentials.

DeploymentSuprSend cloud with 99.9% uptime, or your own VPC, on-prem or BYOC with vendor support on Enterprise. SOC 2 Type II, ISO 27001, GDPR, HIPAA, CPRA.

How your team operates it

In the dashboard

The SuprSend agent builds a workflow from a description, drafts the copy for each channel and traces why a send failed. Product and growth work here and in Slack.

In your own agent

Connect the SuprSend MCP server to Claude, ChatGPT, Cursor or any MCP client and build and change workflows, templates and tenants, test and send, and read the delivery log and analytics from there.

In your IDE or codebase

The SuprSend CLI pushes and pulls workflows, templates, schemas and translation files, promotes staging to production and generates TypeScript types, so a bulk change is one command reviewed in a pull request.

Pricing. Free up to 10,000 notifications a month; Essentials starts at $100 a month for 50,000, then $2 per 1,000; Business starts at $250 a month for 50,000, then $5 per 1,000; Enterprise custom.

Verdict. Choose SuprSend when your product sends its own notifications alongside campaigns and you want one system, one preference set and one log for both; choose Klaviyo when the job is store marketing run by marketers. For the head-to-head, see how SuprSend differs from Klaviyo.

2.Omnisend

Best for online stores that want Klaviyo-style email, SMS and push automations with a faster setup and a lower entry price

Where it goes deep. Omnisend is built for the same buyer as Klaviyo: a store on Shopify, WooCommerce or BigCommerce that wants campaigns and automations without a developer. Prebuilt workflows cover welcome series, abandoned cart, browse abandonment and post-purchase follow-ups, and email, SMS and web push can sit in one workflow. Its free plan matches Klaviyo’s on contacts at 250, with 500 emails a month. Standard allows twelve emails per contact each month, and Pro removes the cap on emails and web push. G2 reviewers give it 9.1 for ease of setup, among the highest scores on this list.

Pricing is by contact, counting subscribers and non-subscribers who sit in your audience. SMS changed in May 2026: for accounts that subscribed from 4 May 2026, SMS is available only on Pro, as a separate credits subscription from $0.007 a message. Omnisend’s MCP server connects Claude, ChatGPT or Cursor to the account; the agent can analyse performance and create campaigns and segments, and a second version adds action-specific tools.

Where it stops. Omnisend is a marketing tool for stores. Product notifications such as password resets and account alerts, an in-app feed, and per-customer setups for a B2B product sit outside what it is built for. Teams that want marketing and product notifications in one place run a second system next to it.

Pick it if you are a store moving off Klaviyo for price or ease, and email, SMS and web push campaigns are the whole job.

Verdict. Omnisend is the closest like-for-like Klaviyo alternative for ecommerce, with an easier setup and lower entry pricing. It covers store marketing and leaves product notifications to another tool.

3.Braze

Best for enterprise consumer brands running journeys across mobile, web and messaging apps for tens of millions of users

Where it goes deep. Braze began as Appboy in 2011, a mobile push company, and built out from there. Canvas journeys carry experiment paths, decision splits, agent steps and version history. Channels include WhatsApp, LINE and KakaoTalk, with Content Cards and Banners for in-app. SQL Segment Extensions build audiences on warehouse data, and Currents streams events back out. BrazeAI Operator works in the dashboard; the remote MCP server reads analytics and creates templates and content blocks.

Where it stops. Contracts are quoted, and Braze counts data points on profile updates, custom events and sessions. Its own stated average time to value is six weeks, and there is no CLI.

Pick it if you have a dedicated marketing operations team and a consumer audience large enough to use journey depth.

Verdict. Braze is the step up from Klaviyo when consumer scale and journey depth matter most. It suits teams with the budget and people to run it.

4.Customer.io

Best for saaS and app companies that want marketers to run event-driven campaigns on product data

Where it goes deep. Customer.io started with email and triggers campaigns from the events your product sends, on people and on objects such as accounts. Essentials costs $100 a month billed monthly and covers 5,000 profiles and a million emails. An in-product agent drafts messages, and its MCP server and CLI act under the signed-in user’s role, with writes held for approval where the client supports it.

Where it stops. There is no free plan, and the bill follows profiles, people and objects together.

Pick it if your audience is product users and your marketers want behavioural campaigns without filing engineering tickets.

Verdict. Customer.io fits products better than stores do. Choose it when campaigns run on product events and marketers own them.

5.Iterable

Best for lifecycle teams at mid-market and enterprise consumer brands that want journeys across email, push, SMS and in-app

Where it goes deep. Iterable, founded in 2013, builds cross-channel journeys with segmentation, A/B tests and personalisation that lifecycle marketers run without engineering. Its MCP server, in beta, gives your agent most of Iterable’s API: it can look up a user, list campaigns, create a template or send an email. It reads by default, and you switch on writes.

Where it stops. Pricing is quoted, with no free plan, and 56% of its G2 reviewers come from mid-market companies. G2 scores its setup at 7.8.

Pick it if you need journey depth close to Braze’s at a mid-market contract.

Verdict. Iterable is a strong Klaviyo replacement for brands outgrowing ecommerce-first tooling. Budget for a contract and an implementation.

6.Brevo

Best for small businesses with large contact lists that want email, SMS and WhatsApp marketing at a low monthly price

Where it goes deep. Brevo prices by emails sent, so a large list you message rarely stays cheap. The free plan sends 300 emails a day, and Starter begins at $9 a month for 5,000 emails. Transactional email runs on the same account as campaigns, and a sales CRM sits alongside. Its MCP server lets an agent manage contacts, create email campaigns and send transactional email, SMS and WhatsApp messages.

Where it stops. SMS and WhatsApp are billed by usage on top of the email plan, and its strength is marketing to a list. Product events, an in-app feed and per-customer setups are outside its focus.

Pick it if price is the main reason you are leaving Klaviyo and your list is bigger than your send volume.

Verdict. Brevo is the low-cost route for marketing and simple transactional email. It suits small teams that want one bill for both.

7.Attentive

Best for ecommerce brands where SMS drives most of their messaging revenue

Where it goes deep. Attentive describes itself as SMS-first, and its depth is there: growing a text list, two-way conversations and SMS journeys, with email alongside. Its MCP server, in beta, lets your agent pull reporting, draft and edit campaigns, and build journeys and segments; changes to live campaigns need write mode switched on.

Where it stops. Contracts are quoted, and the product centres on SMS and email marketing.

Pick it if text messaging is your main revenue channel and you want a vendor that specialises in it.

Verdict. Attentive is the specialist pick for SMS-led brands. Teams whose revenue runs through email do better with a broader platform.

When you should stay on Klaviyo

• You run an online store, and email and SMS campaigns are the whole messaging job.
• Your order and shipping confirmations go through Klaviyo's approved transactional flows, and you rarely change them.
• Your marketers own messaging end to end, and engineering has no notification roadmap.
• You use Klaviyo for more than messaging, such as reviews, forms or its helpdesk, and replacing those is a project of its own.
• Your active profile count stays small enough that the bill does not worry you.

How to migrate off Klaviyo

1. 01Record your baselines. Export a month of delivery, open, click and unsubscribe rates per flow and campaign, so you can compare after the move.
2. 02Rebuild your flows as workflows. Map each flow trigger to an event, then rebuild the steps. In SuprSend, keep the workflows in your repo with the CLI so every change is reviewed.
3. 03Move profiles and push tokens. Export profiles and their properties through the API or the CLI, and register device tokens with the new platform's SDK before you switch sending.
4. 04Carry consent state. Move email and SMS consent, suppressions and unsubscribes per channel and list, so nobody is messaged who opted out.
5. 05Add the in-app inbox. Klaviyo has no feed to port, so this is new work: embed the inbox component and point it at the same workflows.
6. 06Dual-send for a short window. Run one flow on both systems to a small segment, compare against your baselines, then move the rest flow by flow.
7. 07Keep Klaviyo for 30 days. Leave the account in read mode for reporting and late unsubscribes before you close it.
